It is well known reactions which the lithiated carban ions get up acylation, and hydroxy compound is obtained by reducing ketone with LiAlH₄ or NaBH₄.

A reaction of O-acylation is carried out by reacting the obtained hydroxy compound with acetic anhydride under the presence of pyridine, and easily by use of DMAP as a catalyst. The obtained N-t-butyl-sulfonamide is reacted with trifluoroacetic acid, and then t-butyl group is separated to obtain primary sulfonamide of formula(IV).

This process may be easily carried out by a skill person in field of organic compounding technology in accordance with the method disclosed on J. D. Catt and W. L. Matier, J. Org. Chem., 39, 566(1974), ibid 38, 1974(1973), or in the case of treatment of polyphosphoric acid, J. G. Lombardino, J. Org. Chem., 36, 1843(1971). Then, an excess amount(about 0.3M) of trifluoro acetic acide is used, and the reacting solution is stirred at the temperature of 0°˜50° C. for 1˜72 hrs.

The volatile material of the obtained product is evaporated under vacuum, and then the residue is crystalized in solvent such as diethylether, ethylacetate, etc. In the above reaction process, R1 is a functional group which is stable for high reactive reagent.

Test results indicate that the compounds of the present invention are highly active pro-emergent or post-emergent herbicides or plant growth regulants. Many of them have utility for broad-spectrum pre- and/or post-emergency weed control in areas where complete control of all vegetation is desired, such as around fuel storage tanks, ammunition depots, industrial storage areas, parking lots, drive-in theaters, around billboards, highway and railroad structures. Some of the compounds have utility for selective weed control in crops such as wheat and barley. Alternatively, the subject compounds are useful to modify, plant growth.

The rates of application for the compounds of the present invention are determined by a number of factors, including their use as plant growth modifiers or as herbicides, the crop species involved, the types of weeds to be controlled, weather and climate, formulations selected, mode of application, amount of foliage present, etc.

In general terms, the subject compounds should be applied at levels of around 0.05 to 10 kg/ha, the lower rates being suggested for use on lighter soils and/or those having a low organic matter content, for plant growth modifications or for situations where only short-term persistence is required.

Formulations

Useful formulations of the compounds of formula(I) can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly.

Sprayable formulations can be extented in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (1) about 0.1% to 20% surfactant(s) and (2) about 1% to 99.9% solid or liquid inert diluent(s). More specially, they will contain these ingredients in the following approximate proportions:

Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactants to activate ingredient are sometimes desirable, and are achieved by incorporation into the formation or by tank mixing.

Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, N.J., but other solids, either mined or monufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts.

Typical liquid diluents and solvents are described in Marsden, "Solvent Guide", 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; Solution concentrates are preferably stable against phase separation at 0° C. "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, N.J., as well as Sisely and Wood, "Encyclopedia of Surface Active Agents", Chemical Publishing Co., Inc., New York, 1964, list surfactants and recommended uses.

All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc.

The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques.
